Abstract: A structural color changeable material includes a strain body and surface plasmon generating particles. In the strain body, a strain is produced by an external pressure or an internal change. The surface plasmon generating particles generate surface plasmon and are contained in the strain body. The surface plasmon is generated by an incident light with a wavelength of 2400 nm or less. A mean particle size of the surface plasmon generating particles is equal to or less than the wavelength of the incident light. The surface plasmon generating particles are periodically arranged parallel to an in-plane direction of a reflection surface of the incident light.

Abstract: A drive device includes a drive member, a light source, a marker, a detector, a signal processor and a strain controller. The drive member includes at least a material which generates a plasmon. The drive member generates strain in response to input energy. The marker is formed on a surface of the drive member. Strain occurs in the marker in accordance with a deformation of the drive member and the marker reflects or transmits light emitted from the light source. The detector detects a light intensity of light reflected from or transmitted through the marker. The signal processor calculates an amount of strain which occurs in the marker based on the light intensity. The strain controller controls an amount of strain of the drive member based on the amount of strain calculated by the signal processor.

Abstract: A scanning optical apparatus includes a light source, a deflector and an imaging optical system. The deflector deflects a beam emitted from the light source to scan a scanning surface with the beam in a main scanning direction. The imaging optical system focuses the beam on the scanning surface. The imaging optical system includes a first lens having negative power in a sub scanning direction and a second lens having positive power in the sub scanning direction, in which the sub scanning direction is parallel to the scanning surface and perpendicular to the main scanning direction. The power φ1 of the first lens, the power φ2 of the second lens and a magnification β in the sub scanning direction of the imaging optical system satisfy the conditions −1.2≤φ1/φ2≤−0.9 and −1.3≤β≤−0.8.

Abstract: An optical scanning apparatus has a first scanning optical element having a negative power in a sub-scanning direction. A first light beam and a second light beam enter the first scanning optical element through points of an input surface on a same side of a reference surface, which includes an optical axis of the first scanning optical element and being parallel to a main-scanning direction. The second light beam makes a greater angle with the reference surface than the first light beam. A first angle between the reference surface and a principal ray of a first ghost light beam is greater than a second angle between the reference surface and a principal ray of a first normal light beam and is smaller than a third angle between the reference surface and a principal ray of a second normal light beam.

Abstract: A recording medium determination device includes a light emitter, a light detector, and a hardware processor. The light emitter emits inspection light to a recording medium. The light detector detects incident light including at least one of diffuse reflected light of the inspection light emitted to the recording medium and fluorescent light excited by the inspection light in the recording medium. The hardware processor makes a determination depending on a property of the recording medium based on a detection result of first incident light of the incident light in accordance with first inspection light of the inspection light and second incident light of the incident light in accordance with second inspection light of the inspection light obtained by the light detector. The second inspection light has an intensity whose peak wavelength is shorter than the peak wavelength of the first inspection light.
